'rnarwsrorrme DEVICE:

To all whom it may concern:

Be it known that I, Mums CoLLINs Fosrnn, a-subject of the King of Great Britain. and resident-of the city of Regina, in the Prov ince of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Train-Stopping Devices, of which the following is aspecification.

This invention relates to improvements in train stopping devices, and the objects of the invention are to provide an eifective, simple and economical device of this kind for bring ing trains and the like automatically and quickly to a standstill when' rendered necessary through unforeseen circumstances;

The invention consists essentially in the combination with a tripping device on the railway track of means carried by the locomotive adapted to be operated by s'aidtripping device'whereby the air brakes are instantaneously and automatically applied or the train otherwise brought to a stand- V Figure still. i I

l'Vith theTforegcing and other objects in View, reference is now had to the drawings in which like characters of reference indicate correspondingpartsin each figure, and in which:

Figure 1 is a side View of the trip mecha nism of. my device applied to a railway track.

Figure 2 is a similar view, showing the trip lever or arm in operation.

Figure 3 is a top view partly sectional of Figure 1.

Figure 4 is an end view of Figure 1. Figure 5 is an end view of Figure 2. Figure 6 is a sectional side view of the knife mechanism showing the air tube there- 7 is a front elevation of Figure 6. Figure 8 is an end view of Figure 7. Figures 9 and .10 show front and side views respectively of the appliance attached to a locomotive.

Referring to the drawings:

10 is a suitable frame adapted to rest 011 the railroad ties 11 between the fish-plate 12 and the rails 13 and provided with a suitable support 14 at one end thereof and clownwardly bent at the other end. 15 is a rockershaft or arm in the vertically bent end of the frame 10 having mounted thereon the trip arm 17 and the link 18 connected at its other yF -r ttc n Patented Feb, 2 8, 1922.

end to the knife operatingerm 19 on the frame 10 and slidably secured thereto by means-of the bracket 20.

Referring to the knife mechanism carried on the locomotive or other rolling stock, 21 is a plate slidably mounted between the guideways=22 and formed with an aperture 23 therein adapted to receive therethrough the air-brake tube 24 and providedbelow and adJacent to said aperture with a knife or cutter 25. 26 is a suitable roller secured on the 'lowerfend of the plate 21 adapted to con act with the-knife-operatingarm 19 in an inoperative position as hereinafter more fully described. 1

The plate guideways otherwise suitably attached to the locomotive' byiplates provided with bolt apertures 2itherein 'and' the roller 26 is held in place bythebrackets 28. The air tube 24 passes through the aperture 23 in the plate 21 and is coupled at one endto .a pipe 29., in turn connected to a T on the train line leading to the front of the locomotive. The'other end of the tube 21% is provided with a dummy coupler suspendedl-y secured through a chain 31 to the locomotive and'in 'such manner as to clear the tube 2 1 from the knife-edge 25.

is a shut-off valve on the pipe 29 for closing same while the member 24 is being replaced after the operation of stopping a train and 33 is the flange of a railway wheel 3d adapted to turn on the track 13.

From the foregoing the operation of my device will be more or less apparent. The movable trip mechanism 10 having been placed in position on the track (as shown in Figure 1), the moving flanged, wheel of the locomotive will contact with the trip arm 17, forcing it downwardly and causing the knife-operating arm 19 to move upwardly (as shown in Figure 2)., thereby moving upwardly through the roller 26-the plate 21 carrying the knife or puncturingmeans 25 to penetrate the flexible air tube member 24; to release the air therein, and thus cause the air-brakes to be applied auto matically to bring the train to a standstill.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof it is intended that all mat-c 22 are boltedor i ter contained inthe accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

It may be mentioned that my invention is particularly adaptable for'use at interthereon, a frame adapted to fit between the fish-plate and the rail, a rocker-shaft therein, a trip arm on said rocker-shaft, a link mounted on said shaft and connecting with a knife-operating arm slidably secured on the frame, a knifeplate slidably mounted on the locomotive, a roller on the lower end thereof adaptedto contact with the knifeoperating arm, an aperture'in said plate, a flexible air tube member adapted to. pass therethrough coupled at one end to pipe connecting means with the air-brake system of the train and provided at the other end with a dummy coupler loosely suspended and supported from the locomotive, and means for closing said pipe connecting means. 7 v f 2. In a device of the class described in combination with a railroad track and a train thereon, trip mechanism on the track comprising an operating arm and a'trip member adapted in combination with the train Wheel to force said operating arm upwardly, an apertured andslidably mounted plate carried by the train adapted to contact with said operating arm, cutting means on said plate andia flexibleair tube connected with the train air-br'akesystem passing through said plate adjacent to said out 'tlng means, whereby on the operating arm by said train member and flexible tube con nection' with the train brake systemi pass ing therethrough and providedwith fa. dummy coupler and adapted in an opera-v tive position to contact with: said cutting means. I i I 4. In a device of the class describedin claim 1, trip meohanismonthe railroad track adapted to. control an operating n arm, puncturing mechanism carried by the train adapted to be operated by said operating arm and air conveying meansconnectedwith the train air-brake system passing: through said puncturing mechanism' whereby on the trip mechanism being operatedrby the train wheels, the brakes are automatically applied and thetrain stopped. i a
